首发时间:2005-10-12
摘要:简要回顾并总结了近几十年来利用Hough变换检测圆的基本原理和各种算法,并扼要介绍了标准圆快速Hough变换的基本原理和算法,然后详细讨论了如何将两个二维参量统计有效结合起来以判断最优圆参量的各种方法,并进行了比较,接着提出使用模糊直方图代替普通直方图统计的方法,取得了较好的效果,并对它们的检测效率做了初步的比较,文末提出了还需要继续深入进行的工作。

Circle Extraction Using Hough Transformation
Abstract:The paper briefly reviews and summarizes the basic principle and all kinds of algorithms of Hough Transformation which has been applied to the circle detection in recent years. And it also introduces the basic principle and algorithm of the standard quick Hough Transformation of circle detection (SQHTCD) tersely. Then the paper discusses in detail how to combine the two 2-D parameter statistics effectively to judge the best circle parameters and compares them. In the next part, the paper puts forward an idea that fuzzy histogram replaces ordinary histogram to draw the parameter statistics and gets good performance. Then the paper compares the efficiency of detection using the two histograms respectively. At the end of the paper, some future work that must be done are introduced.
Keywords: Hough Transform circle detection fuzzy histogram
